Hello, I noticed from this support thread
that the data for this campaign is not packaged correctly. Could you repackage your campaign by following the instructions in this post
That way, people will have an easier time installing and playing your campaign, since they'll be able to just extract the mod download directly to the root of their Diaspora folder and have it work correctly with both the launcher and the game. Packaging your mod this way will also get the sound files that you've added to work.
If you'd like to learn more about mod packaging, the pre-release campaign checklist
has more information, particularly the section "Where to Put the Files?". There's even more information about it in this wiki article
. Unfortunately, the Diaspora team doesn't have a Diaspora-specific version of this information available right now, but the FS2 version will work for our purposes here.
If you have any questions, please feel free to ask here or on the tech help board.
